IMPROVED ANCHOR.

Specification forming part of Letters Patent N0. 42,346, ,dated April19, 1864.

.T0 all whom it may concern:

Be it known that I, C. A. CHAMBERLIN, of Allegheny City, in the countyof Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Anchors; and I do hereby declare that thefollowingis a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figures l and 2 are longitudinal views at rightangles to each other of an anchor constructed according to my invention.Fig. 3 is a front view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

The main objects of my invention are', first, to insure the anchorcatching quickly in the bottom, and thereby being brought quickly intoposition to hold the vessel; and, second, to obtain an anchor that willhold more in proportion to its weight than an anchor of the ordinaryconstruction.

The improvements consist in certain devices which I term the reverser,77the elevator, and the depressor7 and the guard,77 applied and operatingin combination with the anchor, as hereinafter specified.

To carry out my invention with the greatest advantage, the two iiukes AA of the anchor are arranged side by side, that both may operatesimultaneously and to obtain a firm hold on the bottom, the shank Bbeing forked, as shown in Fig. 1, and one fluke being formed upon orattached to each prong thereof. The two prongs of the shank areconnected by means ofthe reverser, which consists of a bow, C, arrangedopposite to the ilukes or across the back of the anchor and4 bolted tothe two prongs of the shank by screw-bolts a a, and this bow or reverseris strengthened by a stout diagonal brace, D, which connects it with theshank above the fork thereof. The principal object of this reverser isto bring theanchor in such a position that the elevator, which will bepresently described, can act, but it is also very convenient to catchwith grapplin g-hooks when the anchor is lost.

To the upper end of the shank B is attached the elevator E, whichconsists of a piece of iron of a form somewhat resembling an elongatediiuke, as shown in Figs. 1 and 2. This elevator is tted into a mortisein the end of the shank, and secured therein by a pivot, b, upon whichit is free to work in a direction transverse to the nukes A A. Theconcave side of the said elevator is toward that side of the shank' onwhich the flukes are arranged, and its convex side toward that side ofthe shank on which the reverser is arranged. The said elevator isintended to supply the place of the stock commonly employed, but is freefrom the defects of the stock-that is to say, it catches into the groundbetter, and consequently does not require to be so long, and it cannever, under any circumstances, foul the cable. Instead of being appliedat the end of the shank, as described, the elevator may be pivoted toany portion of the length of the shank, so as to be capable of swingingtoward either side in the same manner as when applied to the end. On theback of the shank B', near the upper end thereof, is the depressor F,consisting of a flat fiange'forged upon or rigidly secured to the shankand standing out edgewise therefrom. This depressor has provided in ittwo or more holes, c c, at different distances from the shank for thereception of the pin d of the shackle G, by which the acble is attached,the said pin being inserted into one or the other ofthe said holesaccording to the depth of water in which the anchor is to be used, thehole nearest the shank being used for shallow water, and one fartherfrom the shank being used for deeper water, that farthest off for thedeepest. The depressor is intended to lower the line of draft, so thatthe lukes are kept at the proper angle for holding, and it enables avessel to be anchored more securely in deep water.

On either side of the shank B, nea-r the upper end thereof and set atright angles, or nearly so, to the depressor F, there are two curvedelbow-like pieces of iron firmly secured to the shank. These constitutethe guard. One end of each is welded or otherwise rigidly secured to theshank close below the mortise in which the elevator Works, and the otherend secured in a similar manner lower down the shank. The purpose ofthis guard is to cause the depression of the point of the elevator whenthe anchor comes with its side on the bottom, and thereby enable thesaid point to catch quickly in the bottom and bring the anchor soonerinto position.

The operation of the anchor is as follows:

In most cases, owing to the superior weight of the linkes, it Willstrike the bottom in its proper position. In case, however, of itsfalling on its back the reverser causes it to roll over onto one side,and the point of the ele- Vator, then entering the bottom, causes theend of the shank to which it is attached to be elevated in such mannerthat the anchor will fall over into the proper position for holdin-g-What I claim as my invention, and desire to secure by Letters Patent, is

l. The reverser C, constructed and applied to an anchor, to operatesubstantially as herein speciied.
